WRENCH.

Specification of Letters iatent.

Application filed ir r h'aa, 1916. Serial no; 85,9153.

To all whom it may concern Be it known that I,v LOUIE W. SMITH, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented certain new and useful Improvements in Wrenches; and I do hereby declare the following to be a full, clear, and exact description of the inventiomsu'ch as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful -improvements in wrenches and the principal object of the invention is to provide awrench which is adapted for quick adjustment, and which when adjusted will be held against possible movement.

A further object of the invention is to provide a wrench which may be simply constructed and will be easily operated.

With these and further objects in view, the invention consists in the novel combina tion and arrangement of parts which will be fully set forth in the following specification and accompanying drawing, in which Figure 1 is a longitudinal sectional view through a wrench constructed in accordance with this invention, Fig. 2 is a transverse sectional view on the line 2-2 of Fig. 1, Fig. 3 is a transverse sectional view on the line 33 of Fig. 1, Fig. 4 is a view similarto Fig. 1 of the modified form of my inventionand Fig. 5 is a transverse sectional view through the modification taken on the line 55 of Fig.

Referring to the drawing the numeral 1 designates a shank of a wrench provided with a plurality of notches 2 which'form a plurality of teeth 3 as clearly shown in the drawing. A suitable head 4 is formed at one end of the shank and provides a wrench jaw while the opposite end of the shank is provided with a reduced cylindrical extension 5 having a reduced threaded extension 6 formed thereon. The shank 1 is preferably rectangular in cross section as illustrated in Figs. 2 and 3 and slidably mounted'thereon is a head 7 forming a movable aw member which isprovided with the central rectangular opening 8 for the reception of the shank and the internally screw-threaded sleeve 9, the inner wall of which is spaced outwardly from the shank as clearly shown in the drawing. A pawl 10 is pivoted in a recess 11 formed in the sleeve 9 at the point where the same joins the head 7 and this 7 sleeve on the shank.

Patented Nov. 14,

pawl is adapted for engagement with the teeth3 hereinbefore referred to so as to rigidly hold the jaw against accidentalmo've ment.

In order to provide an adjusting means for the jaw, a suitable'handle 12 is provided and is formed with an inwardly extending flange 13 at one end which is" a'daptedtoengage in the space between the wall formed by the cylindrical portion 5 and the nut 14 which is threaded on the extension 6 so that the handle will be held against longitudinal movement with relation to the shank. It will also be noted however that the handle be rotated with relation to the shank and is provided at the end opposite the flange 13 with the externally screw-threaded cylindrical extension 15 which is adapted to engage the threads on the inner space of the sleeve 9 so that upon rotation of the shank the sleeve 9 and head 7 will be adjusted relatively to the shank and head 4.

Referring to the modified form of the invention as illustrated in Fig. l the numeral 16 designates the shank of the wrench which corresponds with the shank 1 of the wrench previously referred to and this shank 16 is provided with a plurality of notches 17 forming space teeth in connection with which the pivoted pawl 18 carried in the recess 19 of the sleeve 20 cooperate. The shank 16 and sleeve 20'each carry suitable jaw members 21 which are adapted to be adjusted with re lation to each other by the movement of the The end of the shank opposite the jaw member like the end of the shank 1 is provided with a cylindrical extension 22 and a similar reduced threaded extension 23 on which the nut 24 is threaded,

the space between the nut and the end of-the shank forms an angular groove in which the flange 25 of the handle 26 is rotatably mounted. The handle is formed with suitable internal screw-threads which cooperate with screw-threads on the exterior of the sleeve 20 and it can thus be seen that when -the handle is rotated'the sleeve will be adthereby firmly locking the jaw against movement.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be'understood that such changes may be made in the combination and arrangement of parts as will fall within the spirit and scope of the appended claim.

What I claim is A wrench including a shank, a sleeve slidable on said shank, a jaw member mounted at one end of the shank, a jaw member on the sleeve adapted to cooperate with the jaw member on the shank, a plurality of teeth on the shank, a latch adapted to engage the teeth to hold the jaw member in various adjusted positions on the shank, a handle r0- tatable on the shank, means to hold the handle against longitudinal movement with re- LOUIE W. SMITH.
